Water treatment plant Steel Mill Salzgitter
The cooling water circuit consists of pumping stations,
different scale pits with oil separation, from here the water will
be divided into three part streams, each part will be cleaned in
a different way. First part stream goes directly to the cooling
tower basin, second part stream will be treated in a settling
basin with longitudinal scraper and the third part stream will be
cleaned with scale separators and gravel filters. This water
than will be cooled with cooling towers. In the cooling tower
basin all part streams will be collected to be pumped to the hot
strip rolling mill.
Cooling water tanks are installed to realize a huge cooling
water flow for a short while for laminar cooling.
